| 摘 要： | 为了研究高升力系统中开口分段的前缘缝翼对增升装置气动特性的影响,对不同构型生成结构化网格,及其流场进行了大量的数值模拟。在同等状态下,结合不同构型的计算结果,分析了开口分段的前缘缝翼对增升装置气动特性的影响。研究表明,机翼失速不仅与开口宽度有关,而且与前缘缝翼上的开口位置有关。

| Abstract: | In order to get the influence of split slat on wing′s aerodynamics,use the structuring grid to simulate the low speed viscous complex flow around the different split slat.On the same situation,combine with the different computational result of different configuration,and analyze the influence of different split slat on the whole wing′s aerodynamics.The research shows that the stall of wing is not only related with the split distance but also with the position of the split. |
